Abstract
The present invention relates to technology for preparing a functional health-care product by utilizing an embryo of sheep, which mainly solves the defects of low nutrient value, less preparation raw material, large preparation technology difficulty, high cost and long cycle of the prior art. The technology is mainly characterized in that an embryo of sheep is pulped into slurry by an ultralow-temperature pulping machine; then the slurry is put into a drying cavity of vacuum freeze-drying equipment, and thereby, the temperature of the material is reduced to blow the eutectic point; then the material is slowly heated, and the dynamic vacuum degree is kept to be between 70 and 200Pa; solid water in the material is directly sublimated into gas to be extracted, and the sublimated and dried material is prepared into granules or powder granules having the fineness of 20 to 200 meshes by an ultralow-temperature powdering machine.
Description
The present invention relates to a kind ofly use mammiferous embryo and produce the technology of functional health product, the production technology of a kind of freeze-dried powder of sheep embryo by vacuum freezing of more specifically saying so.
The sheep embryo is that ewe is shaped before childbirth or the half form embryo, the collateral tissue Placenta caprae seu ovis is the vital tissue structure of fetus parent nutrient substance exchange, both all contain abundant nutrition and multiple bioactive substance, human body its usability of edible back and absorbability are strong, and the nutrition proportion compatibility is very similar to human body, contain protein more than 82%, the aminoacid kind is complete, wherein contain compositions such as abundant phosphoric acid fat and lecithin, also contain immunoglobulin, multiple antibody and anti-interferon etc.But traditional processing method can make wherein many nutritions and active substance destroyed, and value descends significantly, and eating mouth feel is relatively poor, is not easy to storage, transportation again.
Chinese invention patent 95109067.4 once disclosed " a kind of frozen dry powder of sheep placenta ", and this lyophilized powder is by cleaning Placenta caprae seu ovis, pulverize and adopting freeze drying process to be prepared from.It has solved the shortcoming that traditional diamond-making technique easily makes active ingredient be damaged and stores, transports inconvenience, but there is following shortcoming: the one, only use Placenta caprae seu ovis for making raw material, and do not have the better sheep embryo of more, the effective nutritions of usage quantity for making raw material, the source that makes raw material is restricted, nutritive value is affected, and has also increased production cost to a certain extent; The 2nd, the Placenta caprae seu ovis of cleaning need be worn into 80~200 purpose granules before freezing, this is difficult to accomplish in actual production, both has been to accomplish also can greatly increase production cost, extends manufacture cycle; The 3rd, need make the vacuum of dried case reach 10Pa during lyophilizing, this also is to be difficult to accomplish or can to improve production cost widely in actual production; The 4th, after distillation, need 4~10 hours product dried process, can increase life cycle of the product.
The objective of the invention is to overcome the shortcoming of above-mentioned prior art and provide a kind of and be of high nutritive value, make the process for producing freeze-dried powder of sheep embryo by vacuum freezing that raw material is many, producting process difficulty is little, production cost is low, with short production cycle.
For finishing the foregoing invention purpose, technical solution provided by the present invention is that a kind of process for producing freeze-dried powder of sheep embryo by vacuum freezing, its special character are that the process of this technology is as follows:
(1) handles early stage
Fresh sheep embryo raw material water is cleaned up, do fritter finishing and be placed in the low temperature beater, carry out the low temperature making beating, temperature of charge becomes muddy below-45 ℃ to material during making beating, and the dehydration back is standby;
(2) vacuum lyophilization
A. the material utilization after will pulling an oar divides hopper to be sub-packed in the material disc, and material disc is packed in the dryness storehouse of vacuum freeze, closes door;
B. make material product temperature drop in the dryness storehouse to eutectic temperature, between-26 ℃~-30 ℃, start vacuum system simultaneously, the static vacuum in the dryness storehouse is reached between 50~70Pa;
C. to the dryness storehouse heat supply, material product temperature is slowly risen, dynamic vacuum degree remains between 70~200Pa, making the direct distillation of solid moisture content in the material is that gas is extracted out, when treating that the temperature rise of material product extremely is not higher than 30 ℃, stop going up heat supply, guarantee 8~12 hours whole sublimation drying time;
D. keep deliver from godown half an hour material behind the sublimation drying;
(3) semi-finished product are handled
A. after material delivers from godown, detect its moisture content≤4%;
B. utilize the ultralow temperature powder beater, material is made 20~200 purpose sheep embryo's granule or powders, temperature of charge is below-45 ℃ when beating powder;
C. sheep embryo granule or powder after adopting non-toxic packaging materials to pulverize are packed.
Described in the above-mentioned technical solution to the dryness storehouse heat supply, can be that such one is that material is slowly heated up to intermittently transition heat supply of dryness storehouse utilization, the 2nd, can make the rate of sublimation of moisture content in the material can be too not fast, thereby guarantee the operate as normal of vacuum system.
Employed beater and powder beater can be the various equipment that can place under the low temperature environment making beating or beat powder among the present invention.
The present invention has following advantage compared to existing technology:
1, utilize vacuum freeze under low temperature state, pulpous state sheep embryo material to be freezed rapidly, and low-temperature heat under vacuum state, making the moisture content in the material is gas by the direct distillation of ice, be different from traditional hot air drying, spray drying, dry in the shade, processing method such as air-dry, kept nutritious composition in sheep embryo Central Plains and active substance, kept original color, and made product quality short texture, water absorption strong, water content is low, is convenient to long-term storage and transportation;
2, raw material is only used Placenta caprae seu ovis change the sheep embryo that usage quantity is many, be of high nutritive value into, the source quantity of raw material is increased, the product nutritive value improves, and has also reduced production cost of products to a certain extent;
3, before freezing, use beater to make pulp sheep embryo raw material, treat that re-using powder beater behind the sublimation drying makes into 20~200 purpose granule or powders, can greatly reduce the difficulty of production technology like this, reduce production cost, shorten the production cycle;
Dynamic vacuum degree during 4, with the material sublimation drying is controlled between 70~200Pa, and this is easy to realize in actual production, has also reduced production cost;
5, only need sublimation drying 8~12 hours, shortened the production cycle.
Below will provide a specific embodiment of the present invention.
This process for producing freeze-dried powder of sheep embryo by vacuum freezing process is as follows:
(1) handles early stage
800 kilograms of fresh sheep embryo raw materials are cleaned up with circulating water, do fritter finishing and be placed on making beating in the ultralow temperature making beating, temperature of charge is controlled at below-45 ℃ during making beating, pulls an oar to material to become muddy, and is standby through centrifuge dehydration;
(2) vacuum lyophilization
